Jake:
I think there are more things in heaven and earth than are dreamt of in your conventional wisdom, Horatio. Have '28 Philly Sterlingworth: front trigger set in the left slot; rear in the right. A rather snaggle-toothed arrangement in relation to the guard. I am not one of the legion of fortunate southpaws-- rather one of the rarely privileged righties--but the experience of pulling front to back is much as you describe--easier with this sort of echelon arrangement. Unfortunately or not, the "first" or left barrel is choked tighter than the right in the conventional fashion. This is actually a handy arrangement for skeet doubles 1,2,6 and 7. I have to remember when I step on station 1 that I'm going to pull the rear trigger to get the open barrel for singles. I have no function-based explanation for the reversal of triggers but observe that the halfbassakwardness of all this is what a previous owner desired or a dyslexic gun mechanic created.
